Description
Technical field
The embodiments herein is related to the wave beam for the signal for determining to be sent to user equipment from network node for guiding
Apparatus and method.
Background technology
The communication equipments such as user equipment (UE) are also known as such as movement station (MS), mobile terminal and wireless terminal.User
Equipment can be wireless in cordless communication network or wireless communication system (otherwise referred to as cellular wireless system or cellular network)
Ground communicates.Can be for example via the radio access network (RAN) and possible one or more cores included in cordless communication network
Heart net performs communication between two UE, between movement station and routine call and/or between movement station and server.
The example of wireless communication system is that Long Term Evolution (LTE), Universal Mobile Telecommunications System (UMTS) and the whole world are mobile logical
Letter system (GSM).
Further example is only used as, UE can also refer to the mobile phone with wireless capability, cell phone, meter on knee
Calculation machine or net book etc..UE in this context can be for example can be via (such as another movement of RAN and another entity
Stand or server) transmission voice and/or the portable of data, pocket can deposit formula, hand-held, computer and include formula or vehicle-mounted
The mobile device of formula.
Wireless communication networks cover the geographic area for being divided into cell area, by such as base station (BS) in the geographic area
Access node (such as radio base station (RBS)) service each cell area, radio base station (RBS) sometimes can basis
Used technology or term are referred to as such as " eNB ", " eNodeB ", " NodeB ", " B node " or BTS (base station transceivers
Stand).Thus cell size is based on based on transmit power and also, base station there can be different type, for example, grand eNodeB, family
ENodeB or femto base station.Cell is the geographic area that base station provides radio covering at base station location.Positioned at base station site
A base station can serve one or more cells.In addition, each base station can support a kind of or several communication technology.It is logical
The air interface operated on wireless frequency is crossed, base station is communicated with the UE in base station range.In the context of the disclosure,
" downlink (DL) " is stated for the transmission path from base station to movement station.Statement " up-link (UL) " is used for opposite direction
Transmission path on (that is, from movement station to base station).
Due to the immense success of smart mobile phone, tablet personal computer and other data traffic equipment, mobile data flow is exponentially
Increase.The conventional method for improving data rate in cordless communication network is increase transmission bandwidth.However, due to wireless access system
Increase, usable spectrum become rare.Therefore, the challenge that following wireless access system faces is to find replacement solution
Certainly scheme meets the high request to data rate.
A kind of mode of increased wireless data service is the more BS of deployment and intensive in processing cordless communication network
Dispose cordless communication network.But this can increase interference and lower deployment cost.
For lower deployment cost, the another kind for improving data rate seems that simpler selection is introduced more in base station
More antennas.By using more antennas at transmitter, the signal of transmission can be directed to the user equipment of plan.This
It is referred to as beam forming in the literature.In addition, by many antenna for base station, can also be in identical frequency and/or time resource
It is upper to send payload data to multiple user equipmenies simultaneously.This is commonly known as multi-subscriber dispatching.
When carrying out beam forming, transmitter needs have certain channel knowledge, to know how to change different antennae
The amplitude and phase of element.In LTE, it can be reported by channel reciprocity or by channel condition information (CSI) to obtain
The channel knowledge.In such as transmission mode (TM) 10, UE is arranged to some reference signals (CSI reference signals, CSI-
RS) measure.UE is then with CQI (CQI), order designator (RI) and precoding matrix indicators (PMI)
Form reports CSI in the uplink.Which precoder PMI instructions use at transmitter, i.e., which set to antenna element
A little weights so that energy is sent towards UE.
The another way for obtaining channel knowledge is to send different wave beam, allow UE to measure these wave beams and report one or
Multiple preferable wave beams.In the case where reporting optimum beam, UE only needs instruction to select which wave beam rather than instruction to represent
The precoder index of phase shift.This means UE need to only measure the signal intensity of wave beam without being an attempt to different phase shift and estimation
Corresponding quality.Cell (or in other words, base station) substantial amounts of wave beam can be sent to be surveyed on all possible direction
Amount.However, this can spend substantial amounts of energy and expense in the cell.
Moreover, for high mobility UE and/or narrow data beam, antenna gain may decline rapidly so that Mei Dangji
When station receives feedback, the feedback is no longer valid to a certain extent, so that the efficiency of beam forming selection is poor.Change speech
It, by the CSI reported may quickly become out-of-date due to high-mobility users equipment, so user equipment is possible to connect
Receive by not being most suitably adapted for present position but for the data of the wave beam transmission with front position.
